It’s the worst thing about a smartphone you ask? If your OnePlus 9 Pro not switching on, that’s the biggest issue. You can’t do anything if the screen is blank, black, or the phone won’t switch on. A subset of Android users are experiencing this problem, despite the fact that it doesn’t happen on a large scale.
There are a variety of reasons why this might happen. It could be anything from software to hardware damage depending on the problem your OnePlus 9 Pro has encountered. Software issues are generally easier to fix than hardware ones. In order to fix the OnePlus 9 Pro not switching on, follow these troubleshooting steps:
Charge your OnePlus 9 Pro
It is very common for people to forget or not even be aware that the battery powering the device can drain far beyond the point where it can even react to a power button.
You will not be able to vibrate your OnePlus 9 Pro no matter how many times you press the power button, since the battery has drained well beyond its point. The second example is when the phone turned off due to some glitch and you kept pressing the power button. As it turns out, battery juice is used to turn on the phone. The more you try to press the power button, the less responsive it will get.
Plug in your OnePlus 9 Pro for 10-15 minutes. Then, try to turn on the device. That’s all you need to do. Check if this works or move on to the next step.
Check Power Button [ OnePlus 9 Pro Not Switching On ]
You need to check that as well. The majority of phones now have both Facial Recognition and Fingerprint, so you can use either. The latter does not require you to press the power button to light up the display. In order to activate Facial Recognition, almost every phone requires pressing the power button once. The power button has tens of other uses, so it is used frequently.
If it is damaged, you will need to replace the power button of your OnePlus 9 Pro as this will resolve the issue once and for all. Make sure the power button is not damaged.
Try reviving with a Computer
The next logical step would be to check whether using a computer to troubleshoot the phone just to check whether it works out or not.
- OnePlus 9 Pro should be connected to a PC.
- To ensure that the battery charges a bit, wait a few minutes.
- After a few seconds, disconnect the cable and reconnect it.
- Check if that helps the battery icon to light up, thereby charging the battery and lighting up the display.
- Charge the battery for another 30 minutes.
- Next, try long pressing the power button to revive the screen.
Verify the Charging Port of your OnePlus 9 Pro
Next, you should verify the charging port on your OnePlus 9 Pro, also known as the female port. It needs to be checked to see if it works and whether the pins inside are straight and not bent. If not, electricity will not be able to flow from the cable to the battery.
Of course, you can seek help from a technician nearby. You can actually use a different cable to verify if the port on your OnePlus 9 Pro is working or not. You can also check if there is any debris or dust inside the port as that may pose a problem as well. In the event that the old cable did not latch properly to the charging port, this is the way to go.
What if the Charger Or Cable is the problem
OnePlus 9 Pro not switching on could also be due to a faulty charger or cable. The forces that cable undergo, such as twisting, stretching, compressing, and bending, can lead to its failure since it is often abused. By switching the old cable with a new one, you will be able to determine whether the cable was the problem or if either side of the contraption is damaged, i.e. the charging port/battery or the charging adapter.
In order to check the charging adapter, you can either visit a service center or replace the old adapter (wall unit). If the latter works, the old one is to blame. You may have a problem with your phone’s battery, charging port, or something else.
The Battery has reached the end of life [ OnePlus 9 Pro Not Switching On ]
When did you purchase your OnePlus 9 Pro? Each smartphone’s battery has a lifespan and its performance decreases gradually depending on what it is exposed to. Therefore, you should not compare the battery backup you had originally with the one you are getting now. It is quite possible that the battery has worn out. Therefore, now is the time to replace it.
Of course, this is an assumption if you use the phone too much (which in turn needs frequent charging) or if the phone is a few years old. It turns out buying a new battery is cheaper than fixing the same OnePlus 9 Pro not switching ON because of a display issue if you get the problem diagnosed and check whether the battery’s life has ended. If that’s not the case, read on.
Check whether the Display is fine
A major concern if your OnePlus 9 Pro isn’t switching on is a damaged display. There is a good chance you dropped the phone or dropped something on it, causing the display to malfunction. In either case, the display is likely damaged and will need to be repaired by a technician.
Are there any signs of Liquid Damage?
The first step in verifying hardware components is to determine if your OnePlus 9 Pro has been damaged by water or any other liquid. When this happens, it can damage the phone depending on the severity of the contact. To check for indicators placed strategically on your phone’s upper and lower panels, you can remove the back cover (if possible). If the indicator is discolored, your phone has been damaged.
The damage caused by liquid will have to be fixed. Of course, this will require paying a service center or technician. However, that’s something you will have to do to keep your OnePlus 9 Pro.
Take it to the Service Center [ OnePlus 9 Pro Not Switching On ]
When the screen still does not light up, you may want to visit a local or authorized service center to get it professionally diagnosed. Assuming the OnePlus 9 Pro is still possible, the technician will help determine what’s wrong and how to get it going. Based on the response you get, you can take a call.
Wrapping up
The OnePlus 9 Pro should be able to finally be revived from the Black Screen of Death. Hopefully, most phones should be able to revive themselves unless they’re severely damaged.
